Nomenclatural History

Remarks

Systematics: Ferris (1941d) described Pelliculaspis saying that the type species did not fit in any named genus. However, it does resemble Fissuraspis ulmi and Nicholiella bumeliae.

Structure: Pelliculaspis has two-barred ducts, with gland spines and with the second pygidial lobes bilobulate. Pupillarial, the adult female being completely enclosed within the exuviae of the 2nd stage, this exuviae being very heavily sclerotized and deeply pigmented throughout, both dorsally and ventrally and dehisching about the lateral margins of its pygidium to permit the escape of the larvae. Adult female entirely membranous except for a slight sclerotization of the dorsum of the pygidium and papillations of the ventral side of the abdomen. Pygidium with the lobes forming three pairs of sclerotized teeth, the median and second lobes being bilobulate (Ferris, 1941d).
